FLUSHING APPARATUS FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 538,315, dated April30, 1895.

Application filed March 30 1894.

To all whom it may concern.-

Be it known that I, JOHN G. BEATTIE, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new 5 and usefulImprovements in Flushing Apparatus for Water-Closets, of which thefollowing is a specification.

My invention relates to means for flushing .water closet bowls and inparticular to means whereby the work may be done efiectively with verylittle water and wholly without noise.

The object of my invention is to provide an effective and noiselessflushing tank for water closets and to prevent leakage therefrom.

To this end my invention consists in the combination with a closed airand water tight tank of a pipe leading from the bottom thereof, a valvearranged in the said pipe, avalve operating lever, an automatictime-closin g device in connection with said lever, and means fordrawing down said lever to open said valve and to move said automaticdevice into position for action; and further my invention consists in acombination supply and siphon connection, substantiallyas hereinafterdescribed and as particularly pointed out in the claims.

The invention will be more readily understood by reference to theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a front elevation of a flushing apparatus embodying myinvention, the upper part thereof being in section. Fig. 2 is anenlarged sectional detail of the valve and the connections thereto. Fig.3 is an enlarged detail of the tilting cylinder of the automatic valveclosing apparatus. Fig. 4 is a section thereof on the line of Fig. 3.Fig. 5 is an enlarged view showing the guide for the Valve lever. Figs.6 and 7 are perspective views of the ring and yielding or temporary stoprespectively, which, I employ in connection with the automatic valveclosing device.

As shown in the drawings, 2 represents a water tank which is closed atall points and made both air and water tight. The tank is held up by thepipes beneath it and by a small bracket 3. A pipe 4. leads from thebottom of 50 the tank and a branch therefrom is connected bearings 25.

' with the gate valve 5, from the other side of Serial No: 505,661. (Nomodel.)

which a discharge pipe 6 leads to the water I closet bowl. In Fig. 2 thegate 7 of the valve is shown, the same being arranged to lift upwardlyand the stem 8 thereof extending from 5 5 t the bottom of the gate downto a suitable stuffing box 9 and into a small sleeve 10, whichpreferably has a guide for the lower end of the stem. The valveoperating lever 11 is pivoted upon the arm 12 depending from aconnection 13 fixed on the stuffing box 9. The end of the leverprojects" into a slot in the stem 8, and the sleeve 10 is provided witha long slot 15 to permit movement of the lever. The sleeve 10 at thebottom turns in the elbow and extends from thence to a connection withthe flushing pipe 6. Small check-valve 17 is arranged in the lower part18 0f the sleeve 10 and is adapted to permit the exhaust of any airwhich may be in the pipe 6 during the downflowof water.Furtheranyleakagefrom the stuffing box around the stem-is carried outthrough this valve by means of the discharge pipe.. The supply pipe 19is much smaller than the discharge pipe 6 and is connected by a union 20to the branch 21 of the pipe 4, which branch extends into the pipe 4 andterminates inthe jet or jet opening 22 adapted to project the water intoor toward the valve. For closing the valve quickly and firmly after thetank has been emptied I provide the shifting weight cylinder 23, whichis pivoted in its upper end upon the trunnions 24 in A chain 27 extendsfrom the 85 arm 26 on the upper end of the cylinder dropping therefromto the valve lever 11. In about the middle of the cylinder I provide apartition 28 preferably inclined and having a small opening 29 at thebottom while at the top a go much larger opening 30 is left.

31 represents a small body of mercury or other heavy liquid, which whenthe cylinder is tilted quickly flows over the top of the partition 28and into the other end of the cylin- 5 der. As the cylinder drops intothe slightly inclined position shown in dotted lines in Fig. 1 themercury will be retained in the upper end of the cylinder and can onlyescape from the same through the hole 29 in the bottom of too thepartition. The flow of the mercury is therefore slow and the cylinderwill not drop until sufiicient mercury has passed to counterbalancethat. in the upper end thereof. To hold the cylinder during this time Ipreferably provide a small ring 32 upon the wall 5 and fix upon thechain 27 a small spring piece or disk 33 preferably of rubber and whichis easily drawn through the ring when the valve lever is pulled down bymeans of the pullchain 34.. When the pull and the lever are rero leasedthis rubber disk moves up against the under side of the ring and itsstrength is such as to prevent the cylinder from dropping in place,therefore holding the same in the position shown in dotted lines inFig. 1. When sufr 5 ficient mercury has passed through the small hole 29and into the bottom of the cylinder, to counterbalance the strength ofthis spring, the same will be quickly drawn through the ring, whereuponthe cylinder being freed will drop instantly and with such force as tostrongly and firmly draw down and close the gate-valve. I preferablyprovide a limiting stop to prevent the cylinder being thrown too high,using for the purpose a tie chain 39. It 2 5 is desirable that therubber disk should center in the wall ring, and I therefore provide aguide for the valve lever to prevent lateral movement thereof; andfurther so arrange the fastenings of the chain 27 that said 0 chain willoccupy a vertical position when the lever is drawn down. I furtherprovide several holes in the arm 26,in order that the leverage may beadjusted as required.

The operation of my device may be briefly 3 5 described as follows: Thetank being empty, except for air contained therein, and the valveclosed, water will fiow through the pipe 19 into the pipe 4 and thenceinto the tank, filling the same until the air in the tank has been sofar 0 compressed that its pressure counterbalances that of the watersupply. The valve may then be opened by drawing down the lever 11 andthe strong stream of water emitted from the nozzle or jet 22 will startthe water from the tank, the supply of water from the tank beingquickened and added to by that continuously flowing from the nozzle 22.Sufiicient time will be allowed for the tank to empty; the valve beingheld open by the engagement of the ring and the temporary stop spring onthe chain 27. Instantly when the tension of said spring is overcome, thecylinder will fall and close the valve. After this the passage of thesupply water to the pipe 6 being closed, it will flow into the tank toagain fill the same. The compressed air in the top of the tank aids inexpelling the water, and it is obvious that the tank after eachoperation will be filled with air rushing up the then empty flushingpipe. Hence the tank can never become air bound.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with the closed tank, of a pipeleading therefrom, a valve for closing the outlet from said pipe, aflushing pipe leading from the opposite side of the valve, means foroperating said valve, and an open supply pipe leading into the firstmentioned pipe at a point to project a stream of water through saidvalve, substantially as described.

2. The combination, with the closed tank, of a pipe leading therefrom, avalve for closing the outlet from said pipe, a flushing pipe leadingfrom the opposite side of the valve, means for operating said valve andan open supply pipe leading into the first mentioned pipe at a pointbetween the tank and said valve, and said supply pipe being providedwith a nozzle or jet opening into said pipe adapted to project thestream of water toward the valve, whereby an ejector action is obtainedto draw the water from said tank when the valve is opened, substantiallyas described.

3. The combination, with the closed air and water tight tank, of thepipe leading from the bottom thereof, the valve in said pipe, adischarge or flushing pipe leading from the opposite side of said valve,a combined ejector and supply pipe connected with said pipe between thevalve and the tank, the stem of said valve, an operating lever connectedtherewith, the pipe or sleeve wherein said stem is operated, the branchfrom the lower end of said pipe returning to the flushing pipe wherebyleakage is disposed of, substantially as described.
